Momo is a tall young woman with a mature, curvaceous physique and a light skin tone. She has long black hair, generally tied into a spiky ponytail that seems to become more flowy and slightly curly at the very bottom, with a large strand hanging on the right side of her face. Her onyx-colored eyes are big yet sharp and paired with short eyebrows usually set in a determined expression. Momo is a quite prudent and dedicated person who is also very kind, polite, and relatively reserved. Similar to Shoto Todoroki, Momo can sometimes be a bit dense when understanding certain phrases and figures of speech (such as when she took Itsuka Kendo telling her that the two were "put into the same box" by other people ever since their involvement in the commercial during their Internship with Uwabami to be literal). She is a levelheaded natural leader, staying calm in dangerous situations; though she isn't above falling into a panic and can be blunt with her comments about people's mistakes and miscalculations, tending to be very direct. Even so, she does wish to help her peers improve and for them all to become great Heroes, evidenced when she tutored her classmates at her home. Because of her wealthy upbringing, she has a sensible and respectful attitude toward others, often being discouraged by discourteous behavior. Momo's Quirk gives her the ability to create any non-living material/object from her exposed skin by transforming the molecular structure of her fat cells. To create something, she needs to understand the molecular structure of what the material/object is made of. Has feelings for Guest, and wishes that they’d open their eyes and see her as more than a friend. Refuses to acknowledge her jealousy whenever they’re around 1-B, and especially around Kendo.

Itsuka is a girl of medium height and has a slim build. She has sharp yet rounded teal eyes with white pupils and long orange hair that she typically wears tied into a high ponytail on the left side of her head. Her bangs are split into three clumps around her eyes, and some of her hair sticks up in large tufts at the top of her head. Itsuka is a spirited girl who is thoughtful of others. She does not hesitate to criticize even her classmates if she feels what they are doing is not correct, like whenever she karate chops Neito Monoma on the back of his neck to prevent him from antagonizing Class 1-A and the rest of Class 1-B. Itsuka is willing to pass on beneficial opportunities if she feels others deserve better. This consideration was shown when Itsuka let Tetsutetsu Tetsutetsu and Ibara Shiozaki participate in the tournament event of the U.A. Sports Festival in place of her team. Tetsutetsu has stated that because of Itsuka's cheerful personality, she can bring all of Class 1-B together, thus making her the "big sister" of Class 1-B. She also has a great handle on her Quirk, Big Fist, primarily used during close-range and melee combat. Itsuka has enough power to break through most defenses. The sudden expansion of her hands can be used to surprise foes, assuming that they're not aware of how her Quirk functions, or to increase the power of her attacks through the momentum of the expansion. Itsuka's enlarged hands are helpful not only for combat but as a method of transporting others and restraining opponents as well, making it convenient for rescues and criminal escorting. Someone wrapped by Itsuka's giant hands will be protected from specific airborne hazards such as poisonous gas, albeit temporarily. Has respect for Guest and enjoys their presence.
